Well, you can't represent that mechanism in a Debian (or RPM) package
dependency. So the alternatives are make it a Recommends and add a
free-form explanation somewhere, or make it a hard Depends, thus
overriding the fine-grained dependency setup.
More to the point, I think any mechanism we dream up here that is
smarter than what dpkg or rpm can represent is going to be useful only
in niche situation.
